Design and implementation of dual-redundancy flight control computer system

Rdundancy technology is very important to improve the reliability of system.A kind of new method of dual-redundancy flight control computer system was presented in detail.First,the system architecture and the basic principle working were introduced in brief.Second,how to write multiple-task arithmetic in the embedded real-time operating system of VxWorks was introduced.This dual-redundancy system can improve safety reliability and task reliability effectively,and by using this method,the designed system becomes good real-time and practicable.
